How do I move the whole thing to the left?

I have just started using Mindjet. I created a topic with sub-topics all dropping to the right. All is fine except that the overall map is centered and placed down the page and to the right. I would prefer, at least when I am working on things to have it in the upper left corner instead of just floating about. Fit just changes the place that I am scrolled to. I cannot seem to grab the map and move it. It is the scroll bars that move when I try that. Only thing I can do is to zoom out to eliminate scrollable area but then the map is too small.

I tried that. Rather than move the item around, that moves the viewer's perspective on the item. That is, when I do as you suggest and start dragging to the upper left corder the item appears to move up and to the left but the scroll bars are simply moving down and to the right. What is being moved is viewing area rather than the object. The effect is the same if I am moving about in the preview window in the lower right corner.

What I am trying to do is to have overview of entire area as I am creating a map and not feel there could be some isolated item I forgot about. I would have thought that things would resize dynamically as more and more things are added. When I use a piece of paper I am not prevented from looking at some part of the paper when looking at another. I feel as though I am using magnifier. I would prefer seeing the entire paper area and having the paper expand in size and map items getting smaller as I add things...or at least being able to control that type behavior

I see from the intro videos that what I see as an annoyance is the norm. Emphasis seems to be on map being centered on page whether map is expanding to all directions or from left to right which is how I do things when I use paper. I understand there is an entire ideology behind this so I will try to get used to it or seek an alternative. Thank you.

Like all software, the viewable area is limited by the computer display. The map canvas does expand as you add more items, but it does not automatically change the magnification, because if it did so it would reach the point where the text was no longer legible. You can change the zoom factor with the controls at the bottom right of the screen, and there is also a button that will automatically zoom the map to fit into the current window, although for large maps, this might mean that they are not legible.

There is no reason not to move the map so that the central topic is on the left, and grow the map to the right, if this is more comfortable. There is a "right map" style that you can enable, which will mean the map will only grow on the right of the central topic.

The issue of accessing a large map through a smaller viewport is common across all mind mapping software, and the majority of them deal with it by scrolling or zooming the map. There is one that uses a hyperbolic tree where topics never actually disappear from view but get very small on the "horizon", but since they are not legible, the value of this is not so great.

I understand that zooming out as things are added could make things at some point too small. But that is not really my issue and anyway only occurs at 5th layer or so. I do not get why starting point is some place scrolled down and to the right. Also it is via scrolling that left or right sided map is moved to one side or another the placement on the work area doesn't matter.

There seems to be plenty of space for having both overview and legibility. It seems that design emphasizes very large maps at the cost of smaller ones. This is fine if simply copying a paper map but for direct creation is, I feel, less desirable.

I zoomed out and made font size rediculously large to show what I mean with having a "viewable-centric" look. This is both readable, with plenty of available space and more important, for me, without scrollbars.

I am still not quite sure what you want.... If I draw Maps on paper the maximum size is A3 and I tend to write everything so large I can read it from a distance.
The benefit of Digital mapping is that I can zoom and collaps and still keep my focus.

The fit map function takes care that you do not loose any free floating topic you may have placed somewhere on your pane.

If you wish the map to start at the left you can use
Design tab =>Growth =>RightMap

Have you tried the View tab =>details section=> Focus on topic?
That brings the topic you select to the center whil collapsing all the others.
